Radio transmission apparatus and control apparatus for events rooms as well as corresponding method

Abstract

Radio systems for supplying hearing apparatus in events rooms are of a more convenient design. To this end a radio transmission apparatus is provided for transmission of speech signals in an events room. It possesses a receive device for receiving at least one control signal and a switching device for switching the radio transmission apparatus on and/or off depending on the received control signal. In addition a control apparatus is provided for controlling the radio transmission device, with which speech signals are transmitted in an events room. This control apparatus possesses a detection device to detect a presence or a movement of the radio transmission device in the events room and a transmit device for transmitting a control signal to the radio transmission device depending on the detection result of the detection device. This allows a transmit device of a teacher to be switched off when they leave the classroom.

1. A control apparatus for controlling a radio transmission device to transmit a speech signal in an event room, comprising:
 a detecting device that detects a movement of the radio transmission device in the event room; and 
 a transmitting device that transmits first and second control signals to the radio transmission device depending on the detection, the first control signal switches the said radio transmission device on and the second control signal switches the radio transmission device off; 
 wherein the detecting device comprises two detection units that are built into a door frame of the event room or in front of or behind the door frame in order to detect a direction of the movement of the radio transmission device, 
 wherein the detection units comprise a localization unit that locates the radio transmission device in the event room, 
 wherein the localization unit comprises a plurality of separate directional antennas, 
 wherein the transmission device transmits the first control signal when the localization unit locates the radio transmission device in the event room and transmit the second control signal when the localization unit locates the radio transmission device out of the event room. 
 
     
     
       2. The control apparatus as claimed in  claim 1 , wherein the detecting device detects movements of a plurality of radio transmission devices in the event room. 
     
     
       3. A method for controlling a radio transmission device to transmit a speech signal in an event room, comprising:
 detecting a movement of the radio transmission device in the event room by a detecting device comprising two detection units; 
 building the detection units into a door frame of the event room or in front of or behind the door frame in order to detect a direction of the movement of the radio transmission device; 
 locating the radio transmission device in the event room by a plurality of separate directional antennas arranged in the detection units; 
 transmitting first and second control signals based on the detection, the first control signal switches the radio transmission device on and the second control signal switches the radio transmission device off; 
 operating the radio transmission device depending on the first and second control signals; 
 transmitting the first control signal when the radio transmission device is located in the event room and transmitting the second control signal when the radio transmission device is located outside the event room; and 
 switching the radio transmission device on if the radio transmission device receives the first control signal and switching the radio transmission device off if the radio transmission device receives the second control signal. 
 
     
     
       4. The method as claimed in  claim 3 , wherein the radio transmission device is configured automatically based on the control signal. 
     
     
       5. The method as claimed in  claim 4 , wherein the radio transmission device is switched automatically into a radio channel based on the control signal. 
     
     
       6. The method as claimed in  claim 3 , wherein a plurality of speech signals from a plurality of sound sources are mixed and transmitted by the radio transmission device. 
     
     
       7. The method as claimed in  claim 3 , wherein the radio transmission device receives the control signal in the event room or at an entrance of the event room.
